Description

Die Erfindung betrifft ein Anus-praeter-Versorgungssystem mit einer Basisplatte, die einen eine Ausnehmung umschließenden Anschlußring aufweist, und mit einem mit dem Anschlußring in Eingriff bringbaren, eine Öffnung in einem Beutel umschließenden Rastring, wobei der Anschlußring und der Rastring jeweis mindestens einen, sich im wesentlichen in einer Ebene senkrecht zur Drehachse der beiden Ringe und über einen bestimmten Winkelbereich erstreckenden Vorsprung aufweisen und in eine sich hintergreifende Lage gegeneinander verdrehbar sind.The invention relates to an anus-praeter supply system with a base plate which has a connecting ring which surrounds a recess, and with a locking ring which can be brought into engagement with the connecting ring and which surrounds an opening in a bag, the connecting ring and the locking ring each having at least one essentially in a plane perpendicular to the axis of rotation of the two rings and extending over a certain angular range projection and can be rotated against each other in an engaging position.

Es sind bereits derartige Anus-praeter-Versorgungssysteme bekannt, bei denen zur Verstärkung von Stomata und Fisteln an geeigneter Stelle auf den Körper des patienten eine Basisplatte aufgeklebt wird. Die Basisplatte weist in ihrem mittleren Bereich eine Ausnehmung auf, die auf der dem Körper des Patienten abgewandten Seite von einem Rastring umgeben ist. Das Versorgungssystem umfaßt außerdem einen Beutel, der eine Öffnung aufweist, die von einem zweiten Rastring vollständig umschlossen ist. Die beiden Rastringe sind so ausgestaltet, daß sie in ihrem Querschnitt ein nut- oder federähnliches Profil zeigen, so daß sich die beiden Rastringe in der Art eines Druckknopfes miteinander in Eingriff bringen lassen. Auf diese Weise erfolgt eine dichte und feste Verbindung des Beutels mit der Basisplatte.Anus praeter supply systems of this type are already known in which a base plate is glued to the patient's body at a suitable point in order to reinforce stomata and fistulas. In its central region, the base plate has a recess which is surrounded by a locking ring on the side facing away from the patient's body. The supply system also comprises a bag which has an opening which is completely enclosed by a second locking ring. The two locking rings are designed so that their cross-section shows a tongue or groove-like profile, so that the two locking rings can be brought into engagement with one another in the manner of a push button. In this way, the bag is sealed and firmly connected to the base plate.

Bei dieser Ausgestaltung des Anus-praeter-Versorgungssystems kann die Basisplatte über einen längeren Zeitraum am Körper des Patienten verbleiben, während der Beutel zur Entleerung oder zum Austausch gegen einen anderen Beutel mehrfach abgenommen werden kann. Sowohl zum Lösen der beiden Rastringe voneinander bei der Abnahme des Beutels als auch zum Anbringen eines neuen Beutels ist es bei einem solchen System notwendig, eine Kraft auf den Körper des Patienten einwirken zu lassen, sei es eine Gegenhaltekraft beim Abziehen des Beutels oder eine direkte Druckkraft beim Anschließen eines Beutels. Diese Krafteinwirkung auf den Körper des Patienten führt zu erheblichen Schmerzen, insbesondere bei frisch operierten Patienten.In this embodiment of the anus preter supply system, the base plate can remain on the patient's body for a longer period of time, while the pouch can be removed several times for emptying or in exchange for another pouch. In order to release the two locking rings from each other when the bag is removed and to attach a new bag, it is necessary with such a system to exert a force on the patient's body, be it a counterforce when pulling off the bag or a direct compressive force when connecting a bag. This force on the patient's body leads to considerable pain, especially in freshly operated patients.

Aus der Furcht, derartige Schmerzen hervorzurufen, werden die Rastringe oftmals nicht fest genug aneinander gedrückt, was zur Folge hat, daß das System undicht wird. Eine Undichtigkeit eines derartigen Systems führt nicht nur zu einer erheblichen Geruchsbelästigung, sondern ist auch wegen des Auftretens von Keimen in höchstem Maße unhygienisch.Because of the fear of causing such pain, the locking rings are often not pressed tightly against one another, with the result that the system leaks. A leak in such a system not only leads to considerable odor nuisance, but is also extremely unsanitary due to the appearance of germs.

Andere bekannte Anus-pater-Versorgungssysteme weisen einen fest mit der Basisplatte verbundenen Beutel auf, der an seinem unteren Ende eine Entleerungsöffnung aufweist Diese Beutel können zwar über einen längeren Zeitraum verwendet werden, sie müssen jedoch in regelmäßigen Abständen durch die Entleerungsöffnung entleert werden. Dies ist sowohl für den Patienten als auch für das Pflegepersonal eine sehr unangenehme Angelegenheit. Bei diesen Systemen ist es femer erforderlich, die Entleerungsöffnung des Beutels in entsprechender Weise dicht zu verschließen, was einen erheblichen Aufwand erfordert und nicht immer mit der entsprechenden Sicherheit durchgeführt werden kann.Other known anus pater supply systems have a bag that is firmly connected to the base plate and has a drain opening at its lower end. These bags can be used over a longer period of time, but they must be emptied through the drain opening at regular intervals. This is a very uncomfortable affair for both the patient and the nursing staff. In these systems it is also necessary to seal the emptying opening of the bag in a corresponding manner, which requires considerable effort and cannot always be carried out with the appropriate security.

Es sind auch Anus-praeter-Versorgungssysteme bekannt, bei denen der Beutel, der mit der Basisplatte fest verbunden ist, keine Entleerungsöffnung aufweist, sondern nach jeder Füllung mitsamt der Basisplatte gegen ein komplettes neues Versorgungssystem ausgetauschtwerden muß. Das häufige Wechseln der Basisplatte verursacht dem Patienten ebenfalls starke Schmerzen und ist für ihn ausgesprochen unangenehm. Andererseits erhöhen sich auch die Kosten eines derartigen Systems ganz beträchtlich, da stets die komplette Basisplatte mit ausgetauscht werden muß.Anus praeter supply systems are also known, in which the bag, which is fixedly connected to the base plate, does not have an emptying opening, but has to be exchanged together with the base plate for a completely new supply system after each filling. The frequent changing of the base plate also causes severe pain to the patient and is extremely uncomfortable for him. On the other hand, the cost of such a system also increases considerably, since the entire base plate must always be replaced.

Aus der GB-A-1 579 875 ist ebenfalls ein Anus-praeter-Versorgungssystem mit einer Basisplatte bekannt, die am Körper des Patienten befestigt werden kann und eine Kupplung aus einem ersten und einem zweiten Kupplungselement aus Kunststoffmaterial aufweist, die auf mechanische Weise in Art eines Bajonettverschlusses aneinander befestigt werden können mit einem Abdichtring dazwischen, wobei an dem zweiten Kupplungselement ein Beutel befestigt sein kann. Die bei diesem bekannten Anus-praeter-System zwisen den beiden Ringen vorgesehene Konusdichtung hat jedoch die vorstehend geschilderten Nachteile.From GB-A-1 579 875 an anus praeter supply system is also known with a base plate that can be attached to the patient's body and has a coupling made of a first and a second coupling element made of plastic material, which is mechanically art of a bayonet catch can be attached to one another with a sealing ring between them, wherein a bag can be attached to the second coupling element. However, the cone seal provided between the two rings in this known anus-praeter system has the disadvantages described above.

Aufgabe der Erfindung war es daher, ein Anus-praeter-Versorgungssystem der eingangs geschilderten Art zu schaffen, das bei einfachem Aufbau und einfacher Bedienung einen sicheren und für den Patienten schmerzfreien Wechsel des Beutels ermöglicht.The object of the invention was therefore to create an anus-praeter supply system of the type described at the outset which, with a simple construction and simple operation, enables the bag to be changed safely and painlessly for the patient.

Es wurde nun gefunden, daß diese Aufgabe bei einem Anuspraeter-Versorgungssystem mit einer Basisplatte, die einen eine Ausnehmung umschließenden Anschlußring aufweist, und mit einem mit dem Anschlußring in Eingriff bringbaren, eine Öffnung in einem Beutel umschließenden Rastring, wobei derAnschlußring und der Rastring jeweils mindestens einen, sich im wesentlichen in einer Ebenen senkrecht zur Drehachse der beiden Ringe und über einen bestimmten Winkelbereich erstreckenden Vorsprung aufweisen und in eine sich hintergreifende Lage gegeneinander verdrehbar sind, erfindungsgemäß dadurch gelöst werden kann, daß im Rastring ein zylindrischer, mit dem Beutel verbundener Teil drehbar gelagert ist, der an seiner Zylinderinnenfläche eine axial-radiale Ring-Dichtlippe aufweist, welche die Zylinderaußenfläche des Anschlußringes dichtend umgreift.It has now been found that this object is achieved in a Anuspraeter supply system with a base plate which has a connecting ring which surrounds a recess, and with a locking ring which can be brought into engagement with the connecting ring and which surrounds an opening in a bag, the connecting ring and the locking ring in each case at least have a projection which extends essentially in a plane perpendicular to the axis of rotation of the two rings and over a certain angular range and can be rotated relative to one another in an engaging position, can be solved according to the invention by rotating a cylindrical part connected to the bag in the locking ring is mounted, which has on its inner cylinder surface an axial-radial ring sealing lip which you the outer cylinder surface of the connecting ring tends to embrace.

Gemäß einer bevorzugten Ausgestaltung der Erfindung sind die an beiden Ringen vorgesehenen Vorsprünge als Segmente konzentrischer Kreisringe ausgebildet oder sie bilden den Teil eines Schraubgewindes.According to a preferred embodiment of the invention, the projections provided on both rings are designed as segments of concentric circular rings or they form part of a screw thread.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung weist der Beutel koaxial zum Rastring auf seiner Rückseite eine Öffnung auf, deren Rand konisch ausgebildet ist zur Aufnahme eines Irrigatorschlauches.According to a further preferred embodiment of the invention, the bag has an opening on its rear, coaxial with the locking ring, the edge of which is conical for receiving an irrigator tube.

Das erfindungsgemäße Anus-praeter-Versorgungssystem weist gegenüber dem Stand der Technik wesentliche Vorteile auf. Da die Basisplatte bei einem Wechsel des Beutels nicht mit ausgetauscht zu werden braucht, ergeben sich sowohl in finanzieller Hinsicht erhebliche Vorteile als auch für den Patienten, dem die schmerzbereitende Abnahme und Anbringung einer Basisplatte erspart bleibt. Durch die erfindungsgemäße Ausgestaltung des Anschlußbrings und des Rastrings ist gewährleistet, daß der Beutel beliebig oft von der Basisplatte gelöst bzw. wieder mit dieser verbunden werden kann, ohne daß Druckkräfte aufgebracht werden müssen, welche gegen den Körper des Patienten gerichtet sind. Ein Lösen des Beutels ist deshalb für den Patienten völlig schmerzfrei. Die drehbare Ausgestaltung der Ringe ermöglicht, die Verbindung fast ohne Krafteinwirkung zu lösen bzw. herzustellen. Weiterhin ergibt sich durch die erfindungsgemäße Ausgestaltung der Vorsprünge eine hervorragende Belastbarkeit der Verbindung in axialer Richtung, so daßsichergestellt ist, daß auch in einem Notfall der Inhalt Beutels nicht austreten kann. Da eine Betätigung der Verbindungseinrichtung praktisch ohne Krafteinwirkung erfolgt, ist es möglich, eine wesentlich kleiner dimensionierte Basisplatte zu verwenden bzw. die Basisplatte durch ein entsprechend ausgestaltes Heftpflaster zu ersetzen.The anus preter supply system according to the invention has significant advantages over the prior art. Since the base plate does not have to be exchanged when the bag is changed, there are considerable financial advantages as well as for the patient, who is spared the pain-consuming removal and attachment of a base plate. The configuration of the connecting ring and the locking ring according to the invention ensures that the bag can be detached from the base plate or connected to it again as often as desired without pressure forces having to be applied which are directed against the patient's body. Loosening the bag is therefore completely painless for the patient. The rotatable design of the rings enables the connection to be released or established almost without the application of force. Furthermore, the inventive design of the projections results in an excellent load-bearing capacity of the connection in the axial direction, so that it is ensured that the contents of the bag cannot escape even in an emergency. Since the connection device is actuated practically without the application of force, it is possible to use a base plate of substantially smaller dimensions or to replace the base plate with an appropriately designed adhesive plaster.

Mit Vorteil ist das erfindungsgemäße Versorgungssystem so ausgestaltet, daß die Vorsprünge als Segmente konzentrischer Kreisringe ausgebildet sind. Diese Ausgestaltung ermöglicht eine besonders einfache und preisgünstige Herstellung des Anschlußrings und des Rastrings. Außerdem wird durch diese Ausgestaltung vermieden, daß es zu Klemmungen zwischen dem Anschlußring und dem Rastring bei deren Verdrehung kommt.The supply system according to the invention is advantageously designed such that the projections are designed as segments of concentric circular rings. This configuration enables a particularly simple and inexpensive manufacture of the connection ring and the locking ring. In addition, this configuration prevents jamming between the connecting ring and the locking ring when they are rotated.

Eine vorteilhaft Ausgestaltung des erfindungsgemäßen Versorgungssystem ist auch dadurch gegeben, daß an einem Ende mindestens eines Vorsprungs ein die Drehbewegung begrenzender Anschlag vorgesehen ist Bei dieser Ausgestaltung ist der maximale Verdrehbereich der beiden Ringe gegeneinander in sicherer Weise begrenzt, so daß vermieden wird, daß durch eine zu starke Drehung wiederum ein Lösen beiden Ringe voneinander erfolgen kann. Die Vorsprünge können vorzugsweise auch leicht geneigt angeordnet sein oder an einem Ende mit einer leicht ansteigenden Erhöhung versehen sein, so daß eine zusätzliche Klemmwirkung in der Endposition der Einrastung erreicht wird.An advantageous embodiment of the supply system according to the invention is also provided in that a stop limiting the rotary movement is provided at one end of at least one projection. In this embodiment, the maximum range of rotation of the two rings against one another is limited in a safe manner, so that it is avoided that by a strong rotation in turn can loosen both rings from each other. The projections can preferably also be arranged slightly inclined or be provided at one end with a slightly increasing elevation, so that an additional clamping effect is achieved in the end position of the latching.

Eine günstige Ausgestaltung des erfindungsgemäßen Versorgungssystems ist auch dadurch gegebeb, daß mehrere Vorsprünge vorgesehen sind und daß die Vorsprünge und die Zwischenräume jeweils einen gleichen Kreissektor der Ringe umfassen. Bei dieser Ausgestaltung erfolgt stets eine optimale Zuordnung des Rastrings zu dem Anschlußring, gleichgültig in welcher Drehlage das den Anschlußring tragende Basisteil auf den Körper des Patienten aufgeklebt wurde. Außerdem erhöht sich die mechanische Festigkeit der verbindung zwischen dem Anschlußring und dem Rastring.A favorable embodiment of the supply system according to the invention is also given by the fact that a plurality of projections are provided and that the projections and the gaps each comprise the same circular sector of the rings. In this embodiment, the locking ring is always optimally assigned to the connecting ring, regardless of the rotational position in which the base part carrying the connecting ring was glued to the patient's body. In addition, the mechanical strength of the connection between the connecting ring and the locking ring increases.

Mit Vorteil ist das erfindungsgemäße versorgungssystem auch so ausgestaltet, daß die Vorsprünge als Teil eines Schraubgewindes ausgestaltet sind. Diese Ausgestaltung beinhaltet nicht nur eine besonders einfache und auch für eine ungelernte Pflegeperson problemlose Verwendung des erfindungsgemäßen Anus- praeter-Versotrgungssystems, sondern gibt auch die Möglichkeit, auf eine zusätliche Dichtung zwischen dem Anschlußring und dem Rastring zu verzichten, da diese beiden durch die Steigung des Gewindes gegeneinander in Anlage gebracht werden können.The supply system according to the invention is also advantageously designed such that the projections are designed as part of a screw thread. This configuration not only includes a particularly simple and also problem-free use for the unskilled caregiver of the anus preter supply system according to the invention, but also gives the possibility of dispensing with an additional seal between the connecting ring and the locking ring, since these two are due to the slope of the Thread against each other can be brought into contact.

Um eine wirkungsvolle flüssigkeits- und gasdichte Abdichtung zwischen dem Anschlußring und dem Rastring zu ermöglichen, ist das Versorgungssystem so ausgestaltet, daß im Bereich zwischen den Ringen eine ringförmige Dichtung vorgesehen ist.In order to enable an effective liquid and gas-tight seal between the connecting ring and the locking ring, the supply system is designed in such a way that an annular seal is provided in the area between the rings.

Eine besonders günstige Ausbildung des erfindungsgemäßen Anus-praeter-versorgungssystems ist auch dadurch gegeben, daß der Beutel koaxial zum Rastring auf seiner Rückseite eine Öffnung aufweist, deren Rand zurAufnahme eines Irrigatorschlauchs konisch ausgebildet ist. Durch diese Ausgestaltung ist es auf besonders einfache Weise möglich, eine Spülung mittels des Irrigatorschlauchs vorzunehmen, während der Beutel mit der Basisplatte verbunden ist, so daß das abfließende Wasser problemlos und ohne zu einer verschmutzung der Umgebung zu führen, in dem Beutel gesammelt werden kann. Auf diese Weise kann der Spülvorgang unter sehr einfachen und optimal hygienischen Bedingungen vorgenommen werden. Der Beutel ist mit einem konusförmig ausgebildeten Öffnungsring versehen, der mit einer elastischen Dichtung nach außen abgeschlossen ist. Durch die Dichtung ist der Irrigatorschlauch hindurchstreckbar.A particularly favorable design of the anus preter supply system according to the invention is also provided in that the bag has an opening on its rear side coaxial with the locking ring, the edge of which is conical for receiving an irrigator tube. With this configuration, it is possible in a particularly simple manner to carry out a rinsing by means of the irrigator hose while the bag is connected to the base plate, so that the water flowing off can be collected in the bag without problems and without polluting the environment. In this way, the rinsing process can be carried out under very simple and optimally hygienic conditions. The bag is provided with a conical opening ring, which is closed with an elastic seal to the outside. The irrigator hose can be passed through the seal.

Die besonders bevorzugte Ausführungsform der Erfindung besteht aus drei Einheiten. Die Basisplatte ist mit dem Anschlußring einstückig ausgebildet, der Beutel ist mit einem Zylinderring mit Ringdichtlippe einstückig ausgebildet, und ein Drehteil bildet die dritte Einheit. DerAnschlußring an der Basisplatte bildet mit dem Drehteil eine Art Schraubverschluß, wobei die Dichtungswirkung über die Ringdichtlippe und den Anschlußring erzeugt wird, ohne dabei die Verschwenkbarkeit des Beutels zu beeinträchtigen. Hierdurch ergibt sich eine leichtere Handhabung bei zuverlässiger Abdichtung.The particularly preferred embodiment of the invention consists of three units. The base plate is formed in one piece with the connecting ring, the bag is made in one piece with a cylinder ring with an annular sealing lip, and a rotating part forms the third unit. The connecting ring on the base plate forms with the rotating part a kind of screw cap, the sealing effect being generated via the ring sealing lip and the connecting ring without impairing the pivotability of the bag. This results in easier handling with reliable sealing.

Nachstehend wird das erfindungsgemäße Anus-praeter-Versorgungssystem anhand eines bevorzugten Ausführungsbeispiels in Verbindung mit der beiliegenden Zeichnung näher beschrieben.The anus preter supply system according to the invention is described in more detail below on the basis of a preferred exemplary embodiment in conjunction with the accompanying drawing.

Das in der Zeichnung dargestellte Anus-praeter-Versorgungssystem zeigt eine auf den Körper des Patienten aufgeklebte Basisplatte 2, die in ihrem mittleren Bereich eine Ausnehmung 3 aufweist, die in geeigneter Weise an die Größe der Öffnung des Körpers des Patienten angepaßt wurde und in etwa koaxial zu dieser liegt Bei dem dargestellten Ausführungsbeispiel weist die Ausnehmung 3 der Basisplatte 2 dieselbe Dimension auf wie die Öffnung im Körper des Patienten. Mit der Basisplatte ist ein Anschlußring 4 derart fest verbunden, daß die Ausnehmung 3 der Basisplatte 2 von dem Anschlußring umgeben wird. Die Verbindung des Anschlußrings 4 mit der Basisplatte 2 erfolgt durch ein geeignetes Klebe- oder Fügeverfahren.The anus praeter supply system shown in the drawing shows a base plate 2 which is glued to the patient's body and has a recess 3 in its central region which has been suitably adapted to the size of the opening of the patient's body and is approximately coaxial to this lies in the illustrated embodiment, the recess 3 of the base plate 2 has the same dimension as the opening in the patient's body. A connection ring 4 is firmly connected to the base plate such that the recess 3 of the base plate 2 is surrounded by the connection ring. The connection ring 4 is connected to the base plate 2 by a suitable adhesive or joining method.

Die Zeichnung zeigt ferner einen mit dem Anschlußring 4 in Eingriff bringbaren Rastring 5a, dessen innere Öffnung um einen gewissen Betrag größer ist als die Ausnehmung 3 in der Basisplatte 2. Mit dem Rastring 5a ist ein Beutel 6 fest verbunden. Der Beutel weist eine Öffnung auf, welche dieselben Dimensionen hat wie die Öffnung des Rastrings 5a und mit dieser koaxial angeordnet ist. Der Beutel 6 kann an seinem unteren Ende wahlweise eine Entleerungsöffnung 14 aufweisen, er kann aber auch an seinem unteren Ende geschlossen sein.The drawing also shows a locking ring 5a which can be brought into engagement with the connecting ring 4, the inner opening of which is larger by a certain amount than the recess 3 in the base plate 2. A bag 6 is firmly connected to the locking ring 5a. The bag has an opening which has the same dimensions as the opening of the locking ring 5a and is arranged coaxially therewith. The bag 6 can optionally have an emptying opening 14 at its lower end, but it can also be closed at its lower end.

Der am Beutel 6 befestigte Rastring 5a weist einen inneren zylindrischen Teil 130 auf, von dem eine Ring- Dichtlippe 109 nach innen vorsteht, so daß durch Ineinanderfügen des Rastrings 5a in den Anschlußring 4 eine Abdichtungwirkung erzielt wird. An seinem nach au ßen gerichteten Bereich weist der Rastring 5a mehrere Vorsprünge 31 auf, die unter die vom äußeren Rand des Anschlußrings 4 nach innen weisenden Vorsprünge 17 des Anschlußrings 4 zur Anlage kommen. Auf diese Weise erfolgt eine sichere und stabile mechanische Verbindung zwischen dem Anschlußring 4 und dem Rastring 5a und damit zwischen dem Beutel 6 und dem Körper des Patienten.The locking ring 5a fastened to the bag 6 has an inner cylindrical part 130, from which an annular sealing lip 109 projects inwards, so that a sealing effect is achieved by inserting the locking ring 5a into the connecting ring 4. At its outward-facing area, the locking ring 5a has a plurality of projections 31 which come under the projections 17 of the connecting ring 4 which point inward from the outer edge of the connecting ring 4. In this way there is a secure and stable mechanical connection between the connecting ring 4 and the locking ring 5a and thus between the bag 6 and the patient's body.

Koaxial zur Öffnung des Rastrings 5a kann auf der gegenüberliegenden Seite des Beutels 6 eine Öffnung in Form eines konusförmigen Ringes vorgesehen sein (in der Zeichnung nicht dargestellt), der nach außen mit einer elastischen Dichtung abgeschlossen ist, durch die ein Irrigatorschlauch hindurchsteckbar ist. Der Irrigatorschlauch ist am vorderen Ende mit einer seitlichen Austrittsöffnung für den Austritt der Spüllösung für die Darmspülung ausgerüstet. Wenn die empfohlene Menge Spüllösung in den Darm eingelaufen ist, wird der Konusring aus dem Stoma entfernt und der Irrigatorschlauch aus der Dichtung, die sich danach selbständig schließt, herausgezogen.Coaxial to the opening of the locking ring 5a, an opening in the form of a conical ring (not shown in the drawing) can be provided on the opposite side of the bag 6, which is closed to the outside with an elastic seal through which an irrigator hose can be inserted. The irrigator tube is equipped at the front end with a side outlet opening for the exit of the irrigation solution for the intestinal irrigation. When the recommended amount of irrigation solution has entered the intestine, the conical ring is removed from the stoma and the irrigator tube is pulled out of the seal, which then closes automatically.

Das in der Zeichnung teilweise in der Draufsicht dargestellte Ausführungsbeispiel des Anschlußrings 4 und des Rastrings 5a zeigt bei beiden Ringen jeweils vier (z. T. verdeckte) Vorsprünge 17 und 31. Die beiden Ringe sind punktsymmetrisch aufgebaut und weisen jeweils gleiche Breiten der Vorsprünge 17 und 31 bzw. der Zwischenräume zwischen den Vorsprüngen auf. Durch diese Ausgestaltung ist sichergestellt, daß die beiden Ringe miteinander in Eingriff gebracht werden können, ohne daß eine bestimmte Zuordnung zueinander vorliegen muß.The embodiment of the connecting ring 4 and the locking ring 5a shown partially in the plan view in the drawing shows four (partially hidden) projections 17 and 31 for both rings. The two rings are of point symmetry and each have the same widths of the projections 17 and 31 or the spaces between the projections. This configuration ensures that the two rings can be brought into engagement with one another without a specific association with one another having to be present.

Es kann vorzugsweise jeweils an einem Ende jedes Vorsprungs 31 des Rastrings 5a ein Anschlag vorgesehen sein, der nach dem Einsetzen des Rastrings 5a in den Anschlußring 4 die maximale Drehbewegung begrenzt. Die Anschläge können durch Hochbiegen des Endbereiches der Vorsprünge 17 oder durch separat angeformte Anschläge gebildet sein. Bei dem dargestellten Ausführungsbeispiel sind die Vorsprünge 17 und 31 als Teile konzentrisch zueinandediegender Kreisringe ausgestaltet.A stop can preferably be provided at each end of each projection 31 of the locking ring 5a, which limits the maximum rotational movement after the locking ring 5a has been inserted into the connecting ring 4. The stops can be formed by bending up the end region of the projections 17 or by separately molded stops. In the illustrated embodiment, the projections 17 and 31 are configured as parts of circular rings concentrically to each other.

Bei dem dargestellten Ausführungsbeispiel kann der Anschlußring 4 auch einen zylindrischen Teil aufweisen, an dessen Außenseite der Vorsprung 17 als Teil eines Schraubgewindes ausgeführt ist Der dazugehörige Rastring 5a weist dann ebenfalls einen zylindrischen Bereich auf, der an seiner Innenseite entsprechende Teile eines Schraubgewindes trägt, so daß der Anschlußring 5a und der Rastring 4 mittels der miteinander in Eingriff stehenden Teile des Schraubgewindes in an sich bekannter Weise gegeneinander verschraubt werden können.

  • Die dargestellte Ausführungsform des erfindungsgemäßen Anus-praeter-Versorgungssystems weist im übrigen vorzugsweise die folgenden Besonderheiten auf:
  • Die Basisplatte 2 kann einstückig mit dem Anschlußring 4 ausgebildet sein. DerAnschlußring 4 steht von der Basisplatte 2 vor und weist auf seiner äußeren Mantelfläche unterbrochene Schraubgewindeteile 17 auf.
In the illustrated embodiment, the connecting ring 4 can also have a cylindrical part, on the outside of which the projection 17 is designed as part of a screw thread. The associated locking ring 5a then also has a cylindrical region which carries corresponding parts of a screw thread on its inside, so that the connecting ring 5a and the locking ring 4 can be screwed to one another in a manner known per se by means of the mutually engaging parts of the screw thread.
  • The illustrated embodiment of the anus praeter supply system according to the invention preferably has the following special features:
  • The base plate 2 can be formed in one piece with the connecting ring 4. The connecting ring 4 protrudes from the base plate 2 and has interrupted screw thread parts 17 on its outer lateral surface.

Der Rastring 5a, der am Beutel 6 befestigt ist, weist auf seiner Innenseite einen zylindrischen Teil 130 auf, von dem eine Ring-Dichtlippe 109 nach innen vorsteht, die in radialer Richtung federnd nachgiebig ist. Durch das Ineinanderfügen des Rastrings 5a in den AnschluBring 4 kann eine technisch einfache, aber hinsichtlich ihrer Abdichtungswirkung sehr wirkungsvolle Verbindung zwischen dem Beutel 6 und dem Körper des Patienten erzielt werden. Die beiliegenden Zeichnung läßt erkennen, wie der Beutel 16 mit dem Rastring 5a verbunden ist. Wesentlich ist dabei, daß der mit dem Beutel 6 fest verbundene Rastring 5a innen über die Lippendichtung 109 abgedichtet ist. Das ermöglicht, die Basisplatte innen zu erhöhen, so daß die Verbindung zwischen Anschlußring 4 und der Basisplatte 2 verbessert wird. Ein zusätzlicher Kunststoffüberzug auf der Basisplatte 2 kann damit entfallen.The locking ring 5a, which is fastened to the bag 6, has on its inside a cylindrical part 130, from which an annular sealing lip 109 projects inwards, which is resilient in the radial direction. By inserting the locking ring 5a into the connection ring 4, a technically simple but very effective sealing effect can be achieved between the bag 6 and the patient's body. The accompanying drawing shows how the bag 16 connects to the locking ring 5a that is. It is essential that the locking ring 5a firmly connected to the bag 6 is sealed on the inside via the lip seal 109. This enables the base plate to be raised on the inside, so that the connection between the connecting ring 4 and the base plate 2 is improved. An additional plastic coating on the base plate 2 can thus be omitted.
